NZEB are buildings that over a year are neutral, meaning that they deliver as much energy to the supply grids as they use from the grids. Seen in these terms they do not need any fossil fuel for heating, cooling, lighting or other energy uses although they sometimes draw energy from the grid. [Source: IEA (Laustsen J.) (2008) Energy Efficiency Requirements in Building Codes, Energy Efficiency Policies for New Buildings.]
Energy performance requirements are based on a building’s overall consumption of energy or fossil fuel or the building’s implied emissions of greenhouse gas. [Source: Laustsen (2009) Energy Efficiency Requirements in Building Codes, Energy Efficiency Policies for New Buildings]
A collection of policies and programmes that support the implementation of a common goal.
